Remove Snow Leopard Server and re-install Snow Leopard

I bought a mac mini and intended to use it as a server but ended up using one through my office. I want to convert it back to a regular machine. I try to install my copy of snow leopard but it won't let me. I've tried using the disk utility but I can't figure it out. I've also haven't found any forum threads about it. Can anyone gimme a hand?

You can't install OS X from the OEM disc that came from one Mac onto another Mac. They are machine-specific. You will need to buy a retail copy of OS X.
